SUMMARY: Titans third-string QB Matt Mauck practiced with the first team offense on Wednesday and is expected to get some work on Sunday against the Jaguars. Though it is not unusual for QB Steve McNair to not participate due to injury on Wednesday, backup Billy Volek usually gets the work. "We'll just see what happens. We'll have a better idea later in the week," Titans Coach Jeff Fisher said on Mauck playing Sunday. "As it relates to Billy, we know what Billy can do. Billy has done a great job for us as a reliever. As a starter he's won games. We don't know much about Matt. If we get an opportunity to put him in the game we will. I would like to have an opportunity to evaluate Matt, give him a chance to play and have some fun instead of having to wait until next preseason." What do you think about this article?
